AT24C04C-XHM-T

Microchip Tech · EEPROM · TSSOP-8

AT24C04C-XHM-T from Microchip Tech, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No-connect pin with no internal connection on the 8-lead TSSOP package.
2 A1 input Device address input A1 on the AT24C04C, hard-wired to GND or VCC and internally pulled down to GND if left undriven, with any pull-up resistor not exceeding 10 kΩ.
3 A2 input Device address input hard-wired to GND or VCC, internally pulled down to GND if not driven, with any pull-up resistor not exceeding 10 kΩ.
4 GND power_in Ground reference for the power supply, to be connected to system ground.
5 SDA bidirectional Open-drain serial data input/output that must be pulled high with an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices.
6 SCL input Serial clock that latches SDA input on its rising edge and clocks SDA output on its falling edge, and must be held high when the bus is idle or pulled high by an external resistor.
7 WP input Write-protect input: connecting it to GND allows normal writes, connecting it to VCC inhibits writes to the full array, and it is internally pulled down to GND if left floating.
8 VCC power_in Device power supply pin; all packages operate from 1.7 V to 5.5 V and invalid VCC voltages may produce spurious results.
